[Plugin: Upload Widget] Video upload?

Can you upload a very small file ?
What is the size of the file you try to upload ?
What is the value of “upload_max_filesize=” in your php.ini ?
1- Ckeck you have enough space in destination folder
2- Ckeck the size set in your wordpress option “Max upload file size:”
3- In your php.ini check these options:
max_execution_time = 120
upload_max_filesize = 400M
try to increase these options.
Don’t forget to restart your apache server after any modifications of php.ini

In network admin setting of your WordPress verify that the extensions mov, m4v and mp4 are included in “Upload file types” option.

Thanks for your response.

Yes, I can upload a small jpg.
I’m currently trying to upload a 5MB file, but it keeps timing out.

Maybe a dumb question, but how do I access my php.ini?

php.ini is a configuration file of your web server.
Which server web are you using and on which OS ?

I’m using Dreamhost and Apple IOS 10.6.8.

The site I am trying to use video upload feature on is https://www.groupmagazine.com…it’s in the footer.

As your web site is hosted on the server of a web hosting service provider you don’t have access to the php.ini.
The only thing you can verify is the network admin setting of your WordPress.
Check these two options:
1- “Upload file types”: The extensions mov, m4v and mp4 must be included in this option.
2- “Max upload file size”: If necessary increase the value of this option.
